In this worksheet, students will be challenged to stretch their understanding of food chains. The terms PRODUCER, CONSUMER, PREDATOR and so on are expected to be understood and the worksheet explores the effects of ecological changes on the structure of food chains as well as food webs.

'Food Chains 3' worksheet

Key stage:  KS 2

Curriculum topic:   Animals, including Humans

Curriculum subtopic:   Food Chains

Difficulty level:  

Worksheet Overview

Food chains show how food energy flows through an ecosystem. The arrows in a food chain show the direction of energy, for example:

 

Leaf

 

 

Greenfly

 

 

Ladybird

 

 

Robin

 

 

Hawk
LEAF   GREENFLY   LADYBIRD   ROBIN   HAWK

 

...shows that the energy PRODUCED by the leaves (using sunlight, water and air) is transferred to the CONSUMERS as they eat each other. The TOP PREDATOR is the hawk.

In the following questions think about where organisms feed within the food chain and what would happen to the chain if they were taken out, say by disease.
